Chilled sand in the production process, as the type of organic matter in the sand, sand-casting process in a large amount of gas, if not in the exhaust flow, it is easy to have a stoma, cook in soy, such as fire flame defects. Castings cause of end-of-life. I introduced the use of the casting with ventilation can be brought to justice and effective solution to these problems. According to the request to place a process or ventilation Root rope, or rope around the ventilation in the core can lead to sand-based.Uses: Chilled in the sand in the production process, as the type of organic matter in the sand, sand-casting process in a large amount of gas, if not in the exhaust flow, it is easy to have a stoma, cook in soy, such as fire flame defects. Castings caused by the Scrapped. I used to launch the company's foundry ventilation rope can be used effectively address the issue.Usage: In accordance with the requirements of process root or put a rope ventilation, ventilation can be brought to justice in the core around on the sand-extraction can.Features: The more complex the greater the-sand, the better the results. Ventilation can be brought to justice in the screening at the screen, renewable sources of pollution, not sand.Specifications: Φ2 Φ4 Φ6 Φ8 Φ10 Φ12 Φ14 Φ18 Φ20, and so on   Furan Resin  Casting bake furan resin is applied to large and medium-sized cast of small-scale production of the occasion, the organization is simple, save drying equipment, equipment Sand simple, low-cost mold (available wood or plastic model), high precision castings . Applied to an annual production capacity below 50,000 casting production, with an annual output volume of 50,000 cast, it could be mechanized production pipeline. My factory convention production has four kinds from the hardened resin model: The nitrogen resin, the low nitrogen resin, the low nitrogen resin, the adaptation mechanization continuous production uses from the hardened resin, also has is suitable uses in the single unit manual production from the hardened resin.Technical indicators Furan Resin hard since the technical requirements should be consistent with the provisions of the table. 

 Packaging and storage: metal packaging, 200kg / barrel.Stored in the shade below 25 °C, the shelf life of 12 months.Use:mixed-bake furan resin sand, can be wheeled roller, S-shaped leaves, Mixer Bowl. According to the accession to the amount of resin casting alloy type, the original state of sand and the sand core (type) of the strength requirement of the general 0.8% to 1.5% within the framework of regulation, curing agent for the addition of heavy resin, 40% to 80% (winter To be more cold weather).Strength test, the resin for the addition of 1.5 percent (or re-sand), curing agent for the addition of 50% of the weight resin.Sand Technology:Standard dose of sand reinforced resin increases (in some cases increase enhancer) leakAfter 60 seconds mixed mixed 60 seconds   Curing agentAccording to the casting plant with Furan Resin from the performance of hard preparation of a series of acid curing agent, applicable to all kinds of weather. Since the hard cast Furan Resin with acid curing agent performance indicators in line with the provisions of HG/T2345-1992, in the table below.Furan Resin casting from hard acid curing agent with the performance index
